伦勃朗单人头像

生成一张 4:5 竖版伦勃朗单人头像。中国 60 岁左右女性，深棕短发，穿墨绿色羊毛披肩和黑色上衣，坐在暖棕手绘布背景前，身体微微转向左侧，眼睛看向镜头。主光从左上方打出清晰但柔和的伦勃朗三角光，右侧阴影保留细节，背景有油画般的暖棕纹理。真实棚拍肖像，85mm 镜头，肩颈以上构图，皮肤纹理自然，脸部比例真实，不要过度磨皮。画面内不要出现任何可读文字、logo、水印、首饰品牌或外部标识。

Create a 4:5 vertical Rembrandt single headshot. A Chinese woman around 60 years old with short dark brown hair wears a deep green wool shawl and black top, seated in front of a warm brown hand-painted canvas backdrop. Her body turns slightly left while her eyes look toward the camera. The key light from upper left creates a clear but soft Rembrandt triangle on the cheek, with detail retained in the right-side shadow; the background has oil-painting-like warm brown texture. Real studio portrait photography, 85mm lens, shoulder-and-neck-up composition, natural skin texture, realistic facial proportions, no over-retouching. No readable text, logo, watermark, jewelry brand, or external mark anywhere in the image.
